Abstract

Test strips for an analytical determination of a component in a fluid sample, in particular for the diagnosis of illnesses. Located on a base layer (2) are a sample receiving region (4) and an evaluation region (6) which are connected to one another by a fluid transporting section. Arranged in the evaluation region (6) is a colour forming layer (11) in which an optically detectable change that is characteristic for the analysis takes place. <??>In order in the case of such a test strip to be able to control the orderly wetting of the test layers by means of longitudinal transport and thus to improve the dosing of the sample, there is arranged over the colour forming layer (11) in the evaluation region (6) an absorbent covering layer (7), which in the initial state of the test strip renders the colour of the colour forming layer (11) invisible. The covering layer (7) is in fluid contact with the fluid transporting section. The covering layer (7) and the colour forming layer (11) are constructed such that the colour of the colour forming reagent becomes visible when both layers are wetted by the sample fluid. <IMAGE>
